Primarily, Biomedical Engineers would be involved in extensive research to develop new equipments and instruments to be used in diagnosing and treatment of medical conditions. These new products borne out from these researches are then evaluated for safety and effectiveness. As with any new medical products, the impact of its safe usage is the most important consideration. Usually, radiation emission levels are checked because a certain level of radiation exposure can have adverse effects in human cells and tissues. Included also in the list of things Biomedical Engineers’ research heavily on is the type of materials to be used for artificial organs. Although, current materials used have greatly improved with regards to compatibility, the search for a perfect transplant material that would not trigger the human body’s immune system still remains elusive.
Another important aspect that Biomedical Engineers consider is modeling computer programs that will be used. Notice that all modern equipments have computer programs that accompany them. For example, a Biomedical Engineer hypothesized that equipment can actually count accurately blood platelets without taking blood samples by attaching an x-ray type apparatus in the wrist and at the same time stopping the blood flow in the whole arm where the apparatus will be attached. How the platelets will be counted, what parameters will be used would depend on what model the Biomedical Engineer would use. Like, let’s say, for every 100cc of blood, a corresponding ratio of white blood cells and red blood cells should correspond accordingly and based from these ratios, the number of platelets can be derived with the use of a special program that will compute these ratios. The programs are usually made by computer programmers but the models and parameters of the program can only be thought out by biomedical engineers since they are the ones who know what the device they are making is for.
Assuming, a breakthrough biomedical device has been engineered, Biomedical Engineers are also the only ones capable of explaining how the equipment works. So, naturally, doing the rounds on hospitals to do product demonstrations and sales marketing would also fall on their shoulders.
To trudge on the path of a Biomedical Engineer, knowledge of the practical application of engineering concepts, particularly electrical or mechanical engineering is needed in order to make those special equipments. Knowledge on statistical analysis methods should also prove a useful skill as product evaluation and testing would be part of a Biomedical Engineer’s life.
